Re: Server performance issues?

[Dave Barber]

We've only got two active systems :

 

The ARS 5.1.1/Helpdesk 4 Live system (archaic, albeit reliable hardware)

The ARS 6.3/Helpdesk 6 test system - this is the one I'm working on.  I've just connected to the server via virtual desktop, its running at patch 15.  Tried the same thing - doing an export of the defs related to HPD:HelpDesk, and its freezing at the Export all related.

 

I'll check the developer cache; I'd forgotten about that.

 

Still doesn't adequately explain the crabby performance though, especially on much higher spec hardware, with considerably lower loading (the live server handles definition exports quite nicely, regardless of the number of users, always has done, the test server has just 2 users connected at the moment).

 

Ta,

Dave

I highly recommend turning on and off the Developer Cache mode ONLY when you are working on forms on a production machine (why aren't you working on a dev machine anyhow).  If you can get it, take the old production machine and use it as your dev machine.  This will allow you to run on a smaller scale to see what effects you will have if you are running a larger production machine with hundreds of users.

Dave,
 
One thing that's a little different about how ARS 6.3 works is that there's more initial caching at the client level to speed up performance in subsequent transactions.  This can be controlled to some extent by changing your caching thresholds, and by turning on the Developer Cache Mode for production systems.

 
Mid-Tier is especially susceptible to the caching issue - initial downloads of a large form may take close to a minute.  But once that's done, if recaching isn't required, subsequent updates and normal transactions are very quick.

All,
 
I'm working nicely through the changes required to our test installation of ARS 6.3/Helpdesk 6 (I can't really call it ITSM6 yet), and the server performance isn't looking too good at the moment.

 
When I talk performance, I'm talking about general working in the Admin tool - saving forms/active links and filters, exporting data.  It was slow on our old server (Win2k, ARS 5.1.1, Helpdesk 4, running dual 500mHz processors with 1gig of ram), but its definitely slower on the new server (Win2k3, ARS 6.3, Helpdesk 6, running dual 3gig processors with 4gig of ram).

 
Right now I'm trying to do a definitions back of the helpdesk form, and I've been sitting waiting for what feels like an eternity - go the export defs window open, selected HPD:HelpDesk, and I've done a "Add All Related", and its just hanging.

 
Any suggestions where to look on our servers?  Have to admit that the Admin tool is unpatched though - does anyone expect that I'd have performance improvements in moving to a later patch?

 
Regards,
 
Dave
 
ps.  How to get an ARS 5.1.1 to 6.3/Helpdesk 4 to 6 migration done in less than 2 weeks - I'll tell you by the end of the week, which is my supposed deadline :)
